Data and Reports
Under Seattle's Energy Benchmarking law, the City shares building data with the public annually. Transparency of Seattle's largest building's energy use helps drive the market to reward energy efficiency and create a continuous cycle of improvement and demand for high-performing buildings. To track aggregate trends in performance, the program publishes data on Seattle Open Data and the Energy Benchmarking Map.
